 T. sicarius, Silvestri, Boll. Lab. Zool. R. Sc. Agr. Portici, IX (20th Feb. 1915), 



p. 325, figs. Ixxiv-lxxv. 



A short series, females only. Professor Silvestri, whose type was bred from 

 Chionaspis olivina, Leonardi, from Nefasit, Eritraea, writes that in these Mauritius 

 examples the funicle is a little longer than in his own specimens. 



Coccophagus acanthosceles, sp. nov. (fig. 3). 



An entirely blackish brown species, only the tarsi and the base of the abdomen 

 obscurely paler. 



Fig. 3. Coccophagus acanthosceles, sp. n., $ ; (a) thorax and abdomen ; {h} mandihle 

 (c) mid-leg: femur, tibia, and first tarsal joint (anterior aspect): (d) radius. 



$. Head wider than deep (6 : 5). Eyes large, occupying three-fifths of the depth 

 of the head and separated at the mid frons by exactly the diameter of either ; closely 

 set with small bristles, one of which rises at every alternate angle of the very regular 

 hexagonal facets ; the lower orbits are more divergent, and the lower angles of the 

 eyes are one and four-fifths diameters apart. Below the anterior ocellus there is a 

 narrow groove to shortly before one-half, where it meets the convergent post-scapal 

 grooves of the upper portion of the scrobes, which form an inverted V ; the sockets
